HYDROMETEOROLOGICAL DISCUSSION

1109 AM CDT SUN AUG 2 2015
VALID AUGUST 2 THROUGH AUGUST 7
...GOOD CHANCE FOR SHOWERS AND THUNDERSTORMS CONTINUES IN THE WEST
INTO MONDAY. DRIER THIS COMING WEEK...
...METEOROLOGICAL DISCUSSION...
Isolated thunderstorm rainfall as high as 3 inches fell in portions
of eastern New Mexico during the past 24 hours, as part of a
widespread coverage of showers and thunderstorms throughout New
Mexico, Colorado and northwestern Texas. Scattered coverage with
amount of up to 1 inch was observed in southwestern Texas.
Another round of showers and thunderstorms is expected by
this afternoon and continuing into the night over portions of
Colorado, New Mexico and western Texas. There is a potential for
locally heavy rainfall and flash flooding, especially in the
mountains of northern New Mexico and southwestern Colorado.
An upper level high pressure ridge is anchored over Texas and New
Mexico and will continue to dominate the weather during the next
week. This includes generally hot weather, and a drying trend due to
a shift in the positioning of the upper level high. After one more
good chance for thunderstorms in the west on Monday, any rainfall on
Tuesday into Friday should be isolated and insignificant.
...PRECIPITATION FORECAST...
For Today into Monday morning, Mean Areal Precipitation (MAP)
amounts of 0.25 to 1 inch are forecast for portions of northern New
Mexico and southwestern Colorado, in the mountains. MAP amounts of
0.25 to 0.5 inch are forecast for portions of far northwestern Texas,
southwestern New Mexico, and southeastern Colorado. Lesser amounts
are forecast for the rest of New Mexico and for the rest of
northwestern Texas.
For Monday into Tuesday morning, MAP amounts of 0.25 to 1 inch are
forecast for the Texas Panhandle and for isolated mountain areas in
Colorado and New Mexico. Lesser amounts are forecast for much of the
rest of New Mexico, Colorado, and northwestern Texas.
For Tuesday into Wednesday morning, no significant MAP amounts are
forecast for the WGRFC area.
For Wednesday into Friday morning, no significant MAP amounts are
forecast for the WGRFC area.
Lakes over the northeastern half of Texas are still releasing water
according to regulation rules and schedules. Soil moisture has been
very high across much of Texas from rainfall over the past two
months. However, with the dry spell through July, topsoil continues
to dry out in Texas. The rainfall forecast over the next five days
will not be heavy enough to cause significant runoff except over the
mountainous areas of New Mexico.
...HYDROLOGIC DISCUSSION...
...Trinity Basin...
...Minor Flooding...
Increased releases from Lewisville and Grapevine will push Carrolton
into flood stage for the forecast period. This will be updated as
further release information is acquired from the Corps on their
projections over the next few days.
...Remainder of WGRFC Basins...
The remainder of WGRFC rivers are below criteria, and no significant
rainfall is expected over the forecast period.
